Thanks,
I agree with what you have said however, I need to show that I have connected the RTD to an appropriate barrier, by showing the RTD can withstand the maximum voltage and current that the barrier is capable of producing. Similar to what I have done for the other instrumentaion.
I have an Zone 0 methane zone, with an RTD (PT100) connected to a ABB AI893 Barrier. In order to ensure hazardous area safety i need to ensure this setup complies with the Entity Model or FISCO Model, however I don't know the maximum voltage and current the RTD can handle before it fries...
